LIST FINDER WITII INSERTABLE INFORMATION CARDS BACKGROUND OF THE INVENTION List finders, such as telephone indexes, comprise a plurality of stacked information cards having names, addresses and/or telephone numbers imprinted thereon. The cards are mounted in a holder, having a cover pivotally mounted thereon to selectively expose the cards for information gathering purposes. In order to obtain a selected telephone number, for example, a pointer is moved along the cover and adjacent to a key letter whereupon the cover is opened to obtain the desired information.

Conventional list finders do not normally facilitate expeditious and legible entry of a new listing on the cards. Many such list finders attempt to alleviate such problem by mounting the cards in a loose-leaf fashion in the holder by means of holding rings or the like. Repeated removal and replacement of the cards on the rings tends to fray the portions of the cards adjacent to the'rings to thus render them unusable in that they become displaced laterally in the holder and interfere with opening and closing of the cover. In addition, normally the cards must be taken out of the holder individually to thus make the task of removal and replacement somewhat laborious.

SUMMARY AND OBJECTS OF THIS INVENTION An object of this invention is to overcome the above, briefly described problems by providing an economical and noncomplex list finder which is adapted to have information cards thereof expeditiously removed and replaced in the list finder without damaging same. The list finder comprises a holder having a cover pivotally mounted thereon and a plurality of stacked information cards removably mounted in the holder. In one embodiment of this invention, a clamping device is applied to the end of the cards prior to their insertion into the holder, whereas in a second embodiment, the stacked cards, per se, are inserted into the holder. In both such embodiments, cooperating retaining means between the holder and cards compress the cards into a locked position therein.

' DETAILED DESCRIPTION FIG. 1 illustrates a telephone index type list finder 20 adapted to have information, such as names, addresses and/or telephone numbers, imprinted on a plurality of stacked information sheets or cards 21 of a card cartridge 22. The list finder further comprises a body member or holder 23 which defines a receptacle for removably mounting the card cartridge therein. The holder has a cover or lid 24 pivotally mounted at a forward end thereof by axially aligned pivot pins 25 (one shown). The holder and cover may each comprise a suitably composed rigid plastic or metallic material.

The rearward end of the cover may be manually released from the holder by depressing a tab 26 which is cantilevered on an end of the holder, as shown in FIG. 4. Such depression releases a lug 27, formed on the cover, to permit automatic raising of the cover to its phantom line position shown in FIG. 1, under the biasing force of a torsion spring 28'. One end of the spring engages a bottom panel of holder 23 whereas a second end thereof is hooked around a lug formed as an integral part of the cover. A 1 1 The information cards maybe individually exposed in a conventional manner by selectively moving a pointer 29 along a slot 30 formed in the cover. The pointer may thus be positioned adjacent to a selected indicia, such as a letter of an alphabetized lettering system, formed on the cover. A holding lug (not shown) is connected to the pointer to engage a selected tab 31 (FIG. 3) to permit only a selected number of the cards to be lifted to expose the desired card.

As shown in FIGS. 2 and 3, each card preferably has a hinge line 32, such as a creased or perforated scoreline, formed laterally thereacross to permit the cards to be pivoted thereat. In The FIGS. 1-4 embodiment, card cartridge 22 further comprises an articulated clamping device 33, preferably comprising a molded semi-rigid plastic material, which functions to clamp the ends of the cards together prior to their insertion into holder 23. In particular, V-shaped notches 34 are formed on the ends of the cards to seat on like formed posts or pedestals 35, formed integrally on a U-shaped bottom member 36 of the clamping device.

A U-shaped top member 37 is connected to the bottom member by an intermediate web 38 and parallel hinge or scorelines 39 and 40. The web has a width substantially equalling the composite thickness of cards 21 whereby top member 37 may be pivoted over bottom member 36 to compress the cards therebetween (FIG. 3). Locking means, shown in the form'of a pair of resilient lock tabs 41 and mating slots 42 respectively formed on top and bottom members 37 and 36, retain the card cartridge in a locked position prior to its insertion into holder 23.

Upon such insertion, cantilevered and resilient hook members 43, formed on bottom-member 36, engage mating notches 44 formed in the bottom-plate-of holder 23 (FIG. 4) to provide releasable retention means for normally preventing longitudinal and lateral displacement of the information cards. Such engagement provides cooperating retaining means, along with laterally spaced hold-down. means or ribs 45 (one shown) which .engage and compress top members 37 ;and thus the information cards, to positively retain the card cartridge inthe holder. Alternatively, ribs 45 could be eliminated and such hold-down means could comprise the top surface of top. member 37 which would be constructed to directly engage the flat, opposed inner surface of the holder.

FIGS. 5-12 illustrate various modifications of the card cartridge and holderwherein like numerals depict corresponding construction, havingsimilar functions. However, the numerals appearing in FIGS. 5-12 are accompanied by letters a through e to clearly identify modified constructions. v 4

In the FIG. 5 card cartridge embodiment, a plurality of stacked information cards 21a have holes 34a punched therethrough to facilitate mounting of the cards on vertically disposed posts or pedestals 35a, formed as an integral part of a bottom member 36a of a plastic clamping device 33a. The clamping device further comprises a top member 37a connected to the bottom member by an intermediate web 38a and .parallel scorelines 39a and 40a. Upon pivoting of the top member over bottom member 36a, the ends of posts 35a will project into aligned holes 35a, formed 3 through top member 37a, and locking means comprising resilient lock tabs 41a will snap into locked position in mating slots 42a. The FIG. 5 card cartridge may then be inserted into holder 23 (FIG. 1) to have cantilevered and resilient hook members 43a thereof engage notches 44 of the holder (FIG. 4).
